Choose ImageGovernment Portal Image Size Requirements
Most Indian government job portals and exam websites require your photo and signature to be under 100KB in JPG format. Use the table below to find the exact size limit for your portal and compress accordingly.
Why Do Government Forms Require Images Under 100KB?
Indian government recruitment portals like SSC, UPSC, IBPS, and Railway set strict file size limits for photo and signature uploads. The most common limit is 100KB for photos and 50KB for signatures.
These limits exist because government servers are shared across millions of applicants. Smaller files mean faster uploads, less server load, and faster form processing. If your image exceeds the limit, the portal will reject your application with an error — even if everything else is correct.
iFixImg automatically finds the highest possible quality that still fits within your chosen size limit — so your photo looks as clear as possible while meeting the portal requirements.

Frequently Asked Questions
How do I compress an image to exactly 100KB?
Upload your image on this page, make sure "100 KB" is selected as the target size, and click Download. iFixImg uses a smart binary search algorithm to find the highest possible quality that still fits under 100KB.
Will the compressed image be accepted by SSC and UPSC portals?
Yes. The output image is a standard JPG file under 100KB which meets the requirements of SSC CGL, SSC CHSL, UPSC DAF, IBPS PO, IBPS Clerk, SBI PO, and most other government portals.
What if my image cannot be compressed to 100KB?
For very high-resolution images, iFixImg will reduce the dimensions slightly along with quality to meet the target. You will see a warning if the exact target was difficult to achieve. In that case try the next size up — your portal may accept slightly larger files too.
Is it safe to compress my Aadhaar or passport photo here?
Completely safe. iFixImg processes your image entirely in your browser using the Canvas API. Your photo is never uploaded to any server, never stored, and never seen by anyone. It stays on your device the whole time.
What is the difference between 100KB and 100KB size limit?
Government portals typically mean a maximum of 100 kilobytes (KB) which equals 102,400 bytes. Our tool ensures your compressed image is within this limit. Some portals show 100KB but actually accept up to 120KB — our tool targets 100KB to be safe.
Can I compress a signature image to 50KB for bank exams?
Yes. Click the "50 KB" preset before uploading your signature image. The tool will compress it to under 50KB which is the standard limit for signature uploads on IBPS, SBI, and Railway portals.
How many images can I compress?
Unlimited. Refresh the page or click New Image to compress another photo. There are no daily limits, no account required, and no fees ever.
Does compressing to 100KB reduce the visual quality?
Some quality reduction is unavoidable when targeting a very small file size. However iFixImg finds the best possible quality at the given size — so for a typical passport photo sized 200×250px, the result at 100KB is still very clear and acceptable for all government portals.
